煤矸石/黄土基陶瓷膜支撑体的制备及烧结特性
Preparation and sintering characteristics of coal gangue/loess-based ceramic membrane support
摘要
Abstract
To address the issue of high cost of ceramic membranes,this study utilized gangue and loess as the primary raw materials.CaCO3 was used as the pore-making agent,and carboxymeth-yl cellulose(CMC)was used as the binder to prepare a gangue/loess-based ceramic membrane support.The physical and chemical properties,surface micro-morphology,and phase composi-tion were characterized by SEM,XRD and pressed mercury method.The experimental results in-dicated that an increase in sintering temperature resulted in the formation of new crystalline pha-ses within the carrier.This led to an increase in both the pure water flux and flexural strength of the support body.Meanwhile,with the extension of the holding time,the particle melting phe-nomenon is more significant,leading to a decrease in pure water flux but an increase in the flexur-al strength of the carrier.The gangue/loess-based ceramic membrane carrier showed excellent o-verall performance under the condition of sintering at a temperature of 1 125 ℃ for 2 hours.The carrier showed a pure water flux of 9 102.44 L/(m2·h·MPa),a flexural strength of 12.317 MPa,an acid/base mass loss rate of 6.64％/0.35％,respectively,an apparent porosity of 38.26％and a porosity of 49％.关键词
